FLEXIDYNE
Smoother, Faster Acceleration - Smaller motors may be used -
Motor starts under no load conditions - Smoother starts - Starting
torque can be easily customized
More Efficient Design - Permits use of standard NEMA Design B
motors - High torque or high slip motors not needed - Reduced
voltage starters not needed - Wound rotor motors not needed
More Efficient Running - No slip at running speed means no wear,
no heat, no power loss
Overload Protection - Provides overload protection at overloads
somewhat greater than starting torque - Protection devices to
prevent damage to FLEXIDYNE are available
Low Current Draw - Less than twice the nameplate amperage during
both starting and overload periods - Many electric utilities
recommend FLEXIDYNE
Increased Productivity - Eliminates product spillage and machine
damage due to harsh starts or jammed loads

SPECIFICATION/HOW TO ORDER/NOMENCLATURE
SPECIFICATIONFLEXIDYNE is available in three designs: Drives,
Couplings, and C-Flex Modules to meet most system needs . The Drive
style is designed to mount directly on the motor shaft to provide
an extremely compact unit for belted service . The Coupling style
provides a versatile solution for transmitting torque between
in-line shafts . The C-Flex Module style provides all of the
benefits of regular FLEXIDYNE in a compact package that readily
mounts between C-Face motors and reducers .
HOW TO ORDER
DRIVE STYLESpecify mechanism size and bore size . Select a
sheave from the selection tables found in the
Modifications/Accessories section . Refer to the part number when
ordering .
COUPLING STYLEOn size 5C - specify bore size . A complete
coupling consists of (1) output hub and (1) mechanism .
On larger sizes - specify coupling size, and bore size . A
complete coupling consists of (1) mechanism, including flexible
disc, (1) Poly-Disc flange, and (2) bushings .
Type PH Couplings - specify coupling size, bore size of the
driven end and the motor end . A complete coupling consists of (1)
mechanism, (1) Taper-Lock or Bored-To-Size flange assembly, and (1)
element .
Refer to the part numbers when ordering .
C-FLEX MODULE STYLESpecify the C-Flex unit size and the
FLEXIDYNE mechanism . Refer to the part numbers when ordering .
FLOW CHARGEDetermine the amount of flow charge to be ordered by
referring to the Flow Charge tables in the
Modifications/Accessories section . Choose between cast steel and
stainless . Refer to the part number when ordering .

FLEXIDYNE
SIMPLIFIED SELECTION PROCEDUREThe tables on pages PT3-6 -PT3-7
give FLEXIDYNE mechanism size and amount of flow charge to provide
starting capacities from 100-200% of motor nameplate HP of a NEMA
Design B squirrel cage induction motor . This starting capacity is
satisfactory for most ordinary industrial applications .
The FLEXIDYNE unit sizes shown in the simplified selec tion
tables suggest the most economical FLEXIDYNE mechanism for a given
RPM and HP . In some cases, under the same conditions, there may be
other sizes of FLEXIDYNE which may be utilized .
STEP 1Determine the approximate starting torque percentage for
the application . As a guide, suggested percentages are listed in
the table below .
STEP 2Determine motor speed and HP to be used . Refer to tables
on pages PT3-6 -PT3-7 based on 1760, 1175, or 875 RPM NEMA Design B
motors .
STEP 3Check maximum bore from Selection/Dimensions pages .

Drier 130-150%
Compressors 150-175% Mills (Ball, Pebble) 150-175% Pumps
125-150%
NOTE: Since FLEXIDYNE Drives and Couplings are selected
primarily as torque limiting devices by using the starting torque
percentages shown above, the use of a service factor is not
necessary .

FLEXIDYNEOTHER APPLICATIONS
The information on the previous page provides a simple method of
selecting the FLEXIDYNE mechanism size when used with NEMA Design B
motors under general operating conditions . Selection for any other
application is based on the specific conditions and requirements of
the installation . The power transmitting characteristics of the
FLEXIDYNE unit vary with input speed and amount of flow charge used
. A FLEXIDYNE unit can be adapted to the specific conditions and
requirements of the individual application by using the proper
amount of flow charge .
FLEXIDYNE units are not recommended for variable speed
applications, engines or speeds below 700 RPM.
DODGE engineers welcome inquiries on FLEXIDYNE mechanism
selection for applications not previously cov ered . It is
suggested that their experience be called upon to recommend the
best installation . To contact Dodge engineering please call
864-284-5700 .
Please provide the following information with your request:
Type, HP, RPM, shaft size of motor
Type, RPM, shaft size of driven machine
Frequency of starts, reversals, and overloads
Time required to accelerate
For high inertia loads, WR2
Starting HP and Overload Breakaway HP desired
Functions the FLEXIDYNE unit must perform

5C FLEXIDYNE COUPLINGThe 5C FLEXIDYNE Coupling uses a formed
steel housing and tubular flexible element . See ordering
instructions in table below .
55C thru 11C FLEXIDYNE CouplingsThe 55C thru 11C size FLEXIDYNE
Coupling uses the same flexible disc used in DODGE POLY-DISC
Couplings . The molded polyurethane disc offers longer life and
smoother, quieter operation . Disc has excellent physical
properties yet remains pliable to cushion shock loads and
accommodate misalignment .H and F Flanges, carried in stock, can be
arranged in the position which best suits the application . In H
type the bushing installs from the Hub side of the flange; in F
type from the Face side .Sufficient flow charge is furnished with
each unit .

TYPE PH FLEXIDYNE COUPLINGSThis unique combination of PARA-FLEX
coupling and FLEXIDYNE mechanism offers maximum protection for
motors and driven machines . The FLEXIDYNE unit allows the motor to
accelerate quickly and start the load smoothly while the Para-Flex
coupling permits up to 1° angular misalignment, up to 1/16”
parallel misalignment and 3/32” end float . Consequently, starting
torque can be tailored to the driven load requirements while
torsional and lateral vibration and shock loads are being absorbed
or cushioned .
The driven end of the couplings uses TAPER-LOCK bushings only .
However, the motor end is available as bushed or bored-to-size .
Bored-to-size flanges accommodate larger shafts than possible with
bushed flanges . Smaller size flanges are reversible offering the H
and F position from the same flange . A choice of H or F flanges is
offered for size PX140 .

FLEXIDYNEC-FLEX MODULEC-Flex is a system for easily adapting
stock FLEXIDYNE couplings to conventional AC motor/C-Face reducer
drive combinations . The advantages of this low cost arrangement
include soft start and intermittent overload protection utilizing
popular NEMA-B motors and across-the-line switching . Costly
reduced voltage starters or specially wound motors are not required
. FLEXIDYNE unit operates bi-directionally
(reversing) and allows starting of heavy inertial loads without
oversized motors .
C-Flex fits all standard NEMA C-Face mountings of 56C, 140TC,
180TC and 210TC frame utilized on 1/2 thru 10 HP, 1750 ROM AC
motors . The C-Flex output bearing provides support for
single-bearing reducer types, but is equally suitable for reducers
having two input shaft bearings .

FLEXIDYNEFLEXIDYNE Flow Charge
Cast steel flow charge is furnished unless otherwise specified .
Sufficient amounts for all applications are furnished and included
in the price of each FLEXIDYNE unit . The part numbers listed here
apply only when extra flow charge is ordered or the application
requires stainless steel flow charge .
Flow charge is packaged in a tough transparent plastic bottle
which is graduated and has a handy pour spout . This makes handling
of flow charge easy whether pouring into the unit or removing flow
charge if a change in torque is desired .
Stainless steel flow charge is recommended for applications
subject to excessive moisture, humidity or wide temperature
variations that may cause internal condensation . It may be ordered
to replace that in an existing unit or in place of the cast steel
flow charge when ordering a FLEXIDYNE unit .
Sizes 5, 5CF, and 55 FLEXIDYNE mechanisms use SAE S110 ( .0234,
maximum diameter) steel shot . In sizes 70 and up, SAE S170 (
.0331” maximum diameter) steel shot is used .

The tables on the previous pages list stock sheaves available
for use on FLEXIDYNE Drives from size 55D thru 15D . The size 5D
uses integral sheaves which are shown on page PT3-8 . The 18D
sheaves are made-to-order .
Avoid the use of bored-to-size sheaves which use setscrews which
may distort sleeve or damage bearings . Order sheaves by part
number listed in tables on previous pages PT3-16 - PT3-17 . Refer
to V-Drive tables on Pages PT3-18 - PT3-24 . Information on
made-to-order sheaves is shown below
